Has anyone tried this stuff, and how well does it work??

I curious about this too. It's $200 and for the same price you can buy da-lite fabric cut-to-size at cousinvideo.com

I got a sample of their CRT White product. I could not see the difference between my wall (with flat white ceiling paint) and the sample they sent me. I had to shine my flashlight on the wall just to see if the sample was still there and hadn't fallen off. The same goes for almost any white matte screen material. IMO it would be just a waste of money. And grey materials suck too. Sure they're nice and dark when they need to be, but they throw off all the other colors and make white look grey.

a guy named hraent said in the rear projection forum that he tried one of their rear projection products and said "it works as advertised as far as I can tell" which would be big news because the shots on the goosystems.com galery look too good to be true. (which is why I remain skeptical)

I asked if he could post some pics but he seems to have dissapeared.
